Invasion Risks Posed by Ornamental Freshwater Fish Trade to Southeastern Brazilian Rivers Neotropical Ichthyology, 11(2):433-441, 2013 Copyright © 2013 Sociedade Brasileira de Ictiologia Invasion risks posed by ornamental freshwater fish trade to southeastern Brazilian rivers André Lincoln Barroso de Magalhães1 and Claudia Maria Jacobi2 A model was developed to assess the risk of invasion of ornamental non-native fishes to six rivers in the state of Minas Gerais, southeastern Brazil, with focus on species popularity. Thirty-nine aquarium shops, in six cities, were visited monthly from January to December 2007. In each city, fish species were identified, and their biology and invasion history information was obtained from the literature. We calculated the annual frequency of occurrence and average number of specimens monthly available in stores. Quarterly water temperature and dissolved oxygen data from 1997 to 2007 were obtained for the Velhas, Muriaé, Uberabinha, Sapucaí-Mirim, Doce and Todos os Santos Rivers from public databases. The invasion risk of each species was assessed through a model comprising nine parameters grouped in four variables: (i) Invasiveness (thermal and dissolved oxygen ranges, diet, parental care or fecundity), (ii) History of invasions (establishment), (iii) Propagule pressure (commercial success, comprising annual frequency of occurrence and number of specimens available monthly at stores), and (iv) Invasibility (water temperature and dissolved oxygen in the target river compatible with the species ranges). Of the 345 ornamental fish species for sale, 332 are non-native to either Minas Gerais (n = 151) or Brazil (n = 194). Based on the proposed cutting values, in particular the compatibility between species and recipient thermal ranges, five ornamental non-native species (Cyprinus rubrofuscus, Carassius auratus, Xiphophorus hellerii, Poecilia reticulata, and P. latipinna) can potentially invade the Velhas and Muriaé Rivers, four species (Cyprinus rubrofuscus, Carassius auratus, X. helleri, and P. reticulata) the Uberabinha River, four species (Cyprinus rubrofuscus, Carassius auratus, X. maculatus, and P. reticulata) the Sapucaí-Mirim River, three species (Carassius auratus, X. hellerii, and P. reticulata) the Doce River, and three species (Cyprinus rubrofuscus, P. reticulata, and Amatitlania nigrofasciata) can potentially invade the Todos os Santos River. Six recommendations are suggested to reduce the invasion risk of non-native fish on the rivers surveyed posed by aquarium trade. Um modelo foi desenvolvido para avaliar o risco de invasão de peixes ornamentais não-nativos em seis rios do estado de Minas Gerais, sudeste do Brasil, com foco na popularidade das espécies. Trinta e nove lojas de aquário em seis cidades foram visitadas mensalmente de janeiro a dezembro de 2007. Em cada cidade, as espécies foram identificadas e suas biologias e histórias de invasão foram obtidas da literatura. Calculou-se a frequência de ocorrência anual e quantidade média mensal de exemplares disponíveis nas lojas. Foram obtidas temperaturas trimestrais da água e dados de oxigênio dissolvido de 1997 a 2007 dos rios Velhas, Muriaé, Uberabinha, Sapucaí-Mirim, Doce e Todos os Santos a partir de bases de dados públicas. O risco de invasão de cada espécie foi avaliado através de um modelo composto por nove parâmetros agrupados em quatro variáveis: (i) Invasividade (limite de alcance térmico/oxigênio dissolvido, dieta, cuidado parental ou fecundidade), (ii) Histórico de invasões (estabelecimento), (iii) Pressão de propágulos (sucesso comercial, composto pela frequência de ocorrência anual e número de exemplares disponíveis mensalmente nas lojas), e (iv) Invasibilidade (temperatura da água/oxigênio dissolvido dos rios compatível com o limite de alcance térmico/ oxigênio dissolvido das espécies). Das 345 espécies de peixes ornamentais para venda, 332 são não-nativos para Minas Gerais (n = 151) ou Brasil (n = 194). Com base nos valores de corte propostos, cinco espécies de peixes ornamentais não-nativos (Cyprinus rubrofuscus, Carassius auratus, Xiphophorus hellerii, Poecilia reticulata e P. latipinna) podem potencialmente invadir os rios Velhas e Muriaé, quatro espécies (C. rubrofuscus, C. auratus, X. helleri, P. reticulata) podem invadir o rio Uberabinha, quatro espécies selecionadas (Cyprinus rubrofuscus, Carassius auratus, X. maculatus e P. reticulata) podem invadir o rio Sapucaí-Mirim, três espécies (Carassius auratus, X. hellerii e P. reticulata) podem invadir o rio Doce, e três espécies (Cyprinus rubrofuscus, P. reticulata e Amatitlania nigrofasciata) podem potencialmente invadir o rio Todos os Santos. Seis recomendações são sugeridas para reduzir o risco de invasão por peixes não-nativos nos rios pesquisados, representado pelo comércio de peixes ornamentais.

State. A model was applied to predict probable non-native fish Currently, the global ornamental fish trade generates about invasions through aquarium fish trade in rivers of Minas Gerais US$ 3 billion/year and an equipment and literature industry State. This southeastern Brazilian state is the fourth in size, that exceeds US$ 15 billion/year (Dawes, 2001). In spite of the and the second most populous, with a current population of popularity of fishkeeping, not all amateurs persevere in more than 18 million (Alves et al., 2007). A donor source of adequately caring for their aquaria due to unwelcome species, represented by ornamental fish trade, was identified difficulties such as excessive growth of individuals and and adopted as a vector for deliberate human dumping, in order aggressiveness of some species. Upon giving up their hobby, to create a predictive model that combined biological, historical, many aquarium owners are reluctant to sacrifice their pets, and commercial variables, as proposed by Rixon et al. (2005), and end up discarding them directly in artificial (Fuller et al., with abiotic criteria, as proposed by Chang et al. (2009). 1999) and natural environments (Semmens et al., 2004). The first of these four variables is the invasiveness ability Aquarium dumping, according to Fuller et al. (1999), is of each species, assessed by four parameters: thermal range, the second main cause of non-native species introduction in dissolved oxygen tolerance, type of diet, and parental care or the US. In Brazil, most of the information about fish fecundity (representing reproductive attributes). The introductions concerns escapees from fish farms for food attributes assumed to facilitate the invasion of ornamental production, while reports of aquarium dumping are rare fish were the ability to tolerate changes in water temperature (Magalhães, 2010). Attention has been paid to non-native and dissolved oxygen levels, omnivorous diet (feeding on at ornamental fish species in Brazil, as well as elsewhere in the least two items among organic debris, micro- or macrophytes, world, only after they have settled into a new environment micro- or macro-invertebrates) and either parental care (by (Alves et al., 2007). Once established, it becomes virtually male, female, or both) or high fecundity (high numbers of impossible to eradicate aquatic species (Gozlan et al., 2010). oocytes). These are important prerequisites for the In order to prevent future invasions in Brazilian water bodies establishment of ornamental non-native species in any via aquarium trade, it is necessary to identify species of freshwater body (Moyle & Marchetti, 2006). The second ornamental fish that pose high invasion risks, as well as to variable is the history of worldwide invasions, adapted from monitor the events that may lead to these introductions (such Drake (2007), defined as H = Pe/Pi ×100, where H = history of as new species offered by the market, environmental changes, invasions, Pe = number of countries where the species has and urban growth). successfully established itself, Pi = number of countries where According to Bomford & Glover (2004), simple risk the species was introduced. The third variable is propagule assessment models that predict invasion risk by non-native pressure, estimated by the number of individuals released, a species are a low-cost alternative to guide management primary factor in establishment success (Vander Zanden & policies.

  • Species Composition and Invasion Risks of Alien Ornamental Freshwater
    www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people.

  • Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa)
    Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by M.K. Oliver, Ph.D. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by Michael K. Oliver, Ph.D. Peabody Museum of Natural History, Yale University Updated 24 June 2020 First posted June 1999 The cichlids of Lake Malawi constitute the largest vertebrate species flock and largest lacustrine fish fauna on earth. This list includes all cichlid species, and the few subspecies, that have been formally described and named. Many–several hundred–additional endemic cichlid species are known but still undescribed, and this fact must be considered in assessing the biodiversity of the lake. Recent estimates of the total size of the lake’s cichlid fauna, counting both described and known but undescribed species, range from 700–843 species (Turner et al., 2001; Snoeks, 2001; Konings, 2007) or even 1000 species (Konings 2016). Additional undescribed species are still frequently being discovered, particularly in previously unexplored isolated locations and in deep water. The entire Lake Malawi cichlid metaflock is composed of two, possibly separate, endemic assemblages, the “Hap” group and the Mbuna group. Neither has been convincingly shown to be monophyletic. Membership in one or the other, or nonendemic status, is indicated in the checklist below for each genus, as is the type species of each endemic genus. The classification and synonymies are primarily based on the Catalog of Fishes with a few deviations. All synonymized genera and species should now be listed under their senior synonym. Nearly all species are endemic to L. Malawi, in some cases extending also into the upper Shiré River including Lake Malombe and even into the middle Shiré.

The consequences of these abrupt changes in the outcomes of predator–prey interactions are unknown. Here, we tested the effects of a heat wave and a turbidity pulse on the foraging success of a subtropical cichlid fish (Gymnogeophagus terrapurpura) on amphipods (Hyalella curvispina). We carried out a short-term experiment combining treatments of turbidity (3 and 100 nephelometric turbidity units [NTU]) and water temperature (19.2, 22.2, 25.2 and 27.0 ◦C), considering potential differences given by fish length.
